<i>In</i> <i>situ</i> Generation and Electrophilic Addition Reactions of the Elements of 'XF'

Abstract

Addition of the elements of 'IF' and of 'BrF' to alkenes can be effected by the in situ generation of these electrophiles from the halogen-AgF. For cyclohexene, 3,3,6,6-tetradeuterocyclohexene, methylenecyclohexane, styrene, and indene, these reactions are simple. However, for acenaphthylene, halogen–fluorine exchange and other reactions make the overall reaction quite complex. Electrophilic addition reactions for 1-fluoro-acenaphthylene are also described. The n.m.r. spectra of many of the products are given and discussed in some detail.
